(a) Interpretation: The formula of the complex should be determined. Concept introduction: In photometric titration, absorbance of the solution is measured to determine the endpoint of the titration. This is based on the theory that the absorbance of a solution is directly proportional to the concentration of analyte. A graph is plotted between absorbance versus volume of titrant added.

Solutions

Chapter 14, Problem 14.16QAP
Interpretation Introduction

(a)

Interpretation:

The formula of the complex should be determined.

Concept introduction:

In photometric titration, absorbance of the solution is measured to determine the endpoint of the titration. This is based on the theory that the absorbance of a solution is directly proportional to the concentration of analyte. A graph is plotted between absorbance versus volume of titrant added.

Interpretation Introduction

(b)

Interpretation:

The molar absorptivity of the complex should be determined.

Concept introduction:

The Beer-Lambert Law is:

A=εlc

where,

A − absorbance

ε - molar absorptivity

l − length of the solution light passes through (cm)

c − concentration of solution (mol/L)
